Abstract: A system (100) and method for preparing a corneal graft from a corneo-scleral button for keratoplasty, such as DLEK, DSEK, or DSAEK, are characterized by the combination of a sterile, disposable, artificial anterior chamber (102) for holding a corneo-scleral button, and a sterile, disposable keratome (104, 130) having a cutting blade (136) for cutting a corneal flap or resection from the button. The keratome (104, 130) and the artificial chamber (102) are substantially entirely plastic and disposable, and a reusable control assembly (106, 400) is connected to the keratome (104, 130) by a control cable (402) to automatically cut the button. The control cable (402) includes a shaft (406) movable within a sheath (404). The artificial chamber (102) includes a stand (112) for supporting a corneo-scleral button, and a cap (114, 302) mountable to the stand (112) to hold the button in place while it is cut.

Abstract: A system (20) for ophthalmic surgery includes a control assembly (24) placed away from the patient to prevent contamination, and a sterile disposable microkeratome (22) for performing surgery on a patient's eye. The disposable microkeratome is connected to the reusable control assembly by a cable (28). The microkeratome includes a base that sits on the eye, and a carriage that supports and guides a cutting blade as it moves relative to the base. The base includes a main portion that holds the microkeratome on the eye and a handle that extends away from the main portion. The cable is connected to the microkeratome at an end of the handle spaced from the main portion to help maintain the sterility of that portion of the microkeratome.
